Online In-Situ Fluorescence Spectrometer InView-PL
InView-PL is an online, in-situ fluorescence spectrometer for monitoring photovoltaic thin-film formation. It can be integrated with spin-coating, VCD, annealing, and film-aging equipment to monitor PL, absorption, and scattering signals in real time during film formation, crystallization, and aging. This helps researchers understand crystallization rates and phase-transition dynamics, optimize conditions, control crystallization, improve crystal quality, and increase device efficiency and stability.

Applications
Monitoring perovskite film formation: a high-SNR cooled spectrometer captures weak signals online and in situ during film formation and maintains high-fidelity PL signals during annealing, providing key data for precise process optimization. Monitoring perovskite quantum-dot synthesis: an in-situ PL module precisely controls reaction endpoints; combined with in-situ absorption spectroscopy, it enables accurate, stable reagent dosing and synthesis of quantum dots with precise bandgaps and excellent full width at half maximum. Epitaxial-wafer uniformity inspection: photoluminescence is important for defect inspection. InView-PL offers UV excitation, broad fluorescence coverage and easy integration, suiting most epitaxial-wafer inspection steps. Fluorescence characterization of luminescent materials: many materials, including perovskites and organic emitters, are unstable in water and oxygen and must be kept in a glovebox; InView-PL's compact design conveniently supports fluorescence characterization there. Applications of deep spectroscopy in photovoltaics and optoelectronics.
Key Features
≥10Hz sampling under operating conditions: a large spot and cooled spectrometer combine nondestructive testing with ≥10Hz sampling even at low excitation intensities of ≤0.1sun, fully meeting operating requirements. High-fidelity data: every InView-PL is irradiance calibrated to avoid spectral distortion from detector-response and grating-efficiency differences, providing true, accurate spectra. Single fluorescence probe: excitation output and fluorescence collection use the same lens, ensuring in-situ sampling by design and simplifying rapid deployment of online in-situ solutions. Long working distance: ≥10cm prevents equipment interference; contaminating processes such as CVD can be measured through an external window, and glovebox use is supported. Spectrometer options: uncooled and TEC semiconductor-cooled versions suit different accuracy requirements and budgets. Optional absorption spectroscopy: modular expansion adds absorption measurements.
